Touch module

Abstract

A touch module includes a touch layer, a transparent panel module and a case. The touch layer has at least one sensor and a connection circuit arranged at least partially around the sensor. The transparent panel module is bonded with one side of the touch layer to at least cover the sensor. The case is formed with an opening for receiving the transparent panel module, whereby the transparent panel module is at least partially exposed to outer side. An inner flange is formed along at least a part of the periphery of the opening for concealing where the connection circuit of the touch layer is positioned to achieve better interference protection effect and minimize the possibility of misjudgment and mis-touch.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates generally to a touch module, and more particularly to a touch module with thinner thickness and better interference protection.[0003]2. Description of the Related Art[0004]Following the rapid development of information technologies and communication networks, electronic information products have more and more popularly used in various fields. The capacitive touch panel has become the mainstream of touch control technology. The capacitive touch panel is widely applied to various electronic information products such as cellular phones, laptop computers, walkmans, displays, monitors and AIO. The capacitive touch panel works on the principle that when a finger touches the capacitive touch panel, the capacitance will change to measure the displacement of the finger so as to achieve the object of operation / control.[0005]FIGS. 1 and 1A show a conventional simple capacitive touch panel applied to a...

Benefits of technology

[0016]It is therefore a primary object of the present invention to provide a touch module, which is manufactured without any paint-made frame, so that the manufacturing process is simplified and the cost for the material is lowered. In addition, the touch module has a tidy and beautified appearance.

[0017]It is a further object of the present invention to provide the above touch module in which the connection circuit is directly concealed by the case so that the touch module is protected from any interference of external signal. Only the section corresponding to the sensors is exposed to outer side of the case so that the possibility of misjudgment and mis-touch is minimized.

[0018]It is still a further object of the present invention to provide the above touch module, which has better waterproof effect and is free from the problem of alignment in assembling process. Also, the touch module has better connection strength.

Problems solved by technology

This process complicates the manufacturing procedure and the paint 71 leads to increase of material cost.2. The connection circuit 82 tends to produce noises to interfere with the operation when the finger touches the touch panel without isolation layer.3. Except the colored frame, the surface of the transparent panel 7 is not provided with any means for distinguishing the position of the connection circuit 82.

Due to the seams along the periphery of the touch panel, the touch panel can be hardly waterproof-treated.

This process complicates the manufacturing procedure and the paint 92 leads to increase of material cost.2. The transparent sheet 91 will increase the total thickness of the product.3. It is hard to precisely locate and align the transparent panel 70 with the case 9.4. The transparent sheet 91 will lead to incorrectness of the touch sensing signal and deterioration of transparency.
